The rotary lever clamp with pneumatic position control is especially suited for clamping fixtures with only little space for the installation of workholding elements. Its construction and compact design allows flexible solutions at various installation conditions. The double-acting rotary lever clamps are used in clamping fixtures whose oil supply is made through drilled channels.

To swing down the clamping lever, the linear motion is used pro rata which clamps the workpiece. To unclamp, the clamping lever swings back to where the workpiece can be safely taken out. Clamping levers are not included in scope of supply! You can order standard clamping levers from different materials and various lengths as accessories. The rotary lever clamp can also be assembled with special and self made clamping levers.

The clamping force depends on the length of the clamping lever. The rotary lever clamps with position control are simular to the double-acting rotary lever clamps on data sheet 250-10. Both differently operating variants are interchangeable due the same installation dimensions.


Pneumatic position control:

The clamping levers are equipped with elastic sealing plugs on both sides. The rotary lever clamp has two drilled channels through which compressed air can be condact into the clamping lever guide of the housing. The bore holes are arranged in a way that they are sealed in the clamping position or in the declamping position by the sealing plug of the clamping lever. This generates a pressure increase in the pneumatic line, which can be monitored by using standard pneumatic pressure switches in the respective position. The pressure switch registers the pneumatic pressure rise and generates an electrical signal which is forwarded to the connected control unit.


Special features:
  • Clamping without shear forces
  • Pipeless oil supply
  • Partial retractable housing
  • Individual clamping levers mountable
  • Control of the clamping lever position
  • standard cylinders and special designs available

Operating conditions:

The clamping lever is coupled with the piston rod. On the double-acting rotary lever clamps, the clamping lever is unclamped by the pressure medium. When installing the rotary lever clamps, the flange surface should be adjusted to the height of the workpiece. The clamping point should be in a horizontal position. Workpiece tolerances can be compensated in spite of the short clamping stroke.


Safety instruction:

Rotary lever clamps can generate great forces. Workpieces and fixtures must be suitable for this. During operation, danger of crushing is given. Accident prevention regulations must be observed. The rotary lever clamps must regularly be checked for contamination and cleaned when necessary.

The rotary lever clamp is basically suitable for any mounting position. However, it must be ensured that the chosen installation position does not enable the accumulation of metal shavings in the swing range of the clamping arm during the operation.
